Guides
Ageniella longula
Ageniella longula is a species of spider wasp in the family Pompilidae. As with other members of the genus Ageniella, it likely exhibits ant-mimicry in females, with elongated legs and banded wings that create the illusion of ant-like body segmentation. The species belongs to the accepta species group, which includes at least three North American species characterized by small size and distinctive wing patterns.
Cratichneumon facetus
Cratichneumon facetus is a species of ichneumon wasp described by Cresson in 1867. It belongs to a large genus within Ichneumonidae, a family of parasitoid wasps. The species has been documented through limited observations, with records in iNaturalist indicating its presence in North America. Like other members of its family, it likely functions as a parasitoid of other insects, though specific host relationships remain undocumented.
Neamblymorpha milva
Neamblymorpha milva is a species of ichneumon wasp in the family Ichneumonidae. The genus Neamblymorpha is a small group within this large family of parasitoid wasps. This species was described by Ezra Cresson in 1867. Records indicate it occurs in the northeastern United States, with documented observations from Vermont.
Psorthaspis legata
Psorthaspis legata is a species of spider wasp in the family Pompilidae, first described by Cresson in 1867. Members of the genus Psorthaspis are known as scoliid wasps, characterized by their robust bodies and parasitoid lifestyle. The species has been documented in North America with 279 observations recorded on iNaturalist. Like other pompilid wasps, Psorthaspis species are solitary hunters that provision their nests with paralyzed spiders as food for their larvae.
Virgichneumon zebratus
Virgichneumon zebratus is a species of ichneumon wasp in the family Ichneumonidae, described by Cresson in 1867. The specific epithet 'zebratus' refers to a zebra-striped or banded appearance. As a member of the subfamily Ichneumoninae (tribe Ichneumonini), it is presumed to be a parasitoid of Lepidoptera larvae, though specific host records remain undocumented. The genus Virgichneumon is characterized by distinctive morphological features in the propodeum and areolet wing cell structure.
